• Italian sausage: The star protein—choose spicy or mild depending on your preference, and if using links, you can remove the casing and crumble the meat for even cooking.
• Tomato paste: Adds depth and a concentrated tomato flavor that enhances the sauce’s richness.
• Garlic and onion powder: Layered aromatics that build an irresistible flavor base.
• Beef broth: Prevents the pasta from sticking and gives the sauce a savory, meaty undertone without overpowering.
• Crushed tomatoes: Bright and tangy, they create the classic tomato sauce texture we all crave.

• Mozzarella cheese: Melts to perfection on top, making the dish irresistibly creamy and cheesy.

How to Make One Pot Italian Sausage Spaghetti Recipe

Step 1: Brown the Sausage

Start by adding the Italian sausage meat straight into your soup pot or Dutch oven over medium-high heat. Use a spoon to break it up as it browns evenly, which takes about 8-10 minutes. Getting that rich brown crust on the sausage builds the deepest flavor right from the start. Don’t forget to drain any excess fat for a lighter finished dish.

Step 2: Build the Flavor Base

Next, stir in the tomato paste and minced garlic, cooking just a minute until fragrant and well combined. Then add the onion powder, sugar, dried oregano, and a pinch of crushed red pepper flakes if you want a subtle kick. This layer of seasonings is what makes this recipe so mouthwatering and truly Italian-inspired.

Step 3: Add Liquids and Pasta

Pour in the beef broth and crushed tomatoes, then crank up the heat to bring it all to a boil. Once boiling, add the uncooked spaghetti directly to the pot. Let it cook uncovered for about 12 minutes, stirring occasionally to prevent sticking. Adjust the heat to maintain a steady simmer so the pasta absorbs all those rich flavors without drying out or boiling over.

Step 4: Melt the Mozzarella and Finish

Turn off the heat and sprinkle shredded mozzarella on top. Cover the pot and let it sit for 5 minutes to allow the cheese to melt luxuriously into the sauce. Give everything a gentle toss to evenly distribute the gooey goodness, then season with salt and pepper to taste. Your beautiful, saucy One Pot Italian Sausage Spaghetti is ready to serve!

How to Serve One Pot Italian Sausage Spaghetti Recipe

Garnishes

Freshly grated parmesan cheese is an absolute must—it adds that salty, nutty finish against the rich sauce. Brighten up each plate with chopped fresh parsley or basil to inject a pop of green and fresh herbal lift. A drizzle of good olive oil can also add silkiness and extra flavor.

Side Dishes

This dish pairs wonderfully with a crisp, simple green salad dressed in vinaigrette or some garlicky roasted vegetables. Warm garlic bread or a crusty baguette is perfect for mopping up any leftover sauce—because there will definitely be some!

Creative Ways to Present

For a fun twist, serve the spaghetti in individual shallow bowls and top with a fresh basil leaf or edible flowers for a pop of color. You can also layer it in a wide casserole dish to serve family-style, letting everyone scoop their perfect portions of cheesy goodness. Adding a sprinkle of toasted pine nuts or freshly cracked black pepper adds beautiful texture and aroma.

Instructions

1. Cook the Italian sausage: Add the Italian sausage meat to a soup pot or Dutch oven over medium-high heat. Cook until browned, about 8-10 minutes, breaking up the meat with a spoon as it cooks. Drain any excess fat.
2. Add tomato paste and garlic: Stir in the tomato paste and minced garlic. Cook together for 1 minute until fragrant.
3. Season the sauce: Add onion powder, sugar, dried oregano, and crushed red pepper flakes if using. Stir to combine all the flavors.
4. Add liquids and bring to boil: Pour in the beef broth and crushed tomatoes. Increase the heat to high and bring the mixture to a boil.
5. Cook the spaghetti: Once boiling, add the uncooked spaghetti. Cook uncovered for about 12 minutes, stirring occasionally to prevent sticking. Adjust the heat down to medium or medium-low to maintain a steady simmer without a rapid boil. Monitor the liquid level, adding a splash more broth if necessary to prevent drying out.

Notes

• Cooking times can vary depending on your stove and pot. Adjust heat as needed to keep a steady simmer and add extra beef broth if the liquid reduces too quickly before the pasta is done.
• For the Italian sausage, any variety amounting to approximately 16 ounces (1 pound) works. You can use ground sausage meat or remove sausage meat from casings if using whole sausages.
• 8 ounces of spaghetti is half of a standard American package, so you can adjust quantity as needed.
